Examples
In this simple example we add a listener to the notifications.onClosed
event to listen for system notifications being closed. When this occurs, we log an appropriate message to the console.
browser.notifications.onClosed.addListener(function(notificationId) { console.log('Notification ' + notificationId + ' has closed.'); });
